ATTACK
LEVEL -
(Black)
With
AL
set at
^
(down)
there
is
no
effect.
Moving
AL
up
to
+5
and
then playing
a
note causes
the
sound
to get
"thinner"
(less
fundamental and
more
harmonics) and
to then
move
back
to the
sound you
have
set
with
the
HPF
and
LPF
sliders,
it
is
as
though
you
moved
the
HPF
and
LPF
sliders
up
past the ''steady" setting
and
then
brought
them
down
together.
[32]
ATTACK
TIME -
(Black)
The
A
slider
adjusts
how
long
it
takes
for
the
filter
envelope
to
move
from
the "fattest"
sound
to the
"thinnest"
sound
(these
points being
set
by
the
I
L and/or
AL
sliders).
SHORT
(slider
down)
causes
a
fast
move
that
sounds
li
ke
a
"blip/
whereas
LONG
(slider
up) causes
a
gradual
change
in
tone.
[33]
DECAY
TIME
-
(Black)
The
D
slider
adjusts
how
long
it
takes
for
the
filter
envelope
to
move
from
the
"thinnest"
sound
to
the
"steady"
sound
set
with
the
HPF
and
LPF
sliders.

RELEASE
TIME -
(Yellow)
The R
slider
adjusts
how
long
it
takes
for
the
filter
to return to the IL
setting after
you
let
go
of the
key
or keys.
If
the IL
slider
is
set at
^
(down), then
R
sets
how
long
it
takes
for
the
filter
to return to the
"steady"
setting after
you
release
the key.
If
IL
and
AL
are
both
at
^,
then
R
has
no
effect.
By
experimenting
with the
VCF
envelope,
you
will
find that
many
useful effects
can be achieved,
including whistle
and
rushing
wind.
Brass
sounds
are
greatly
enhanced
by
the use
of IL
and
AL
with
moderate
attack
and decay
times.
To
get
a
very sharp
"blip"
for
extremely
percussive
sounds,
set
AL
up
to
+5
and
set
attack
and decay
at
the shortest
time
(down).
You
will
also find
that the
VCF
envelope
and
VGA
envelope can
be
manipulated
together
to get
still
more
variations
in
effect.
